Abstract
The multispectral detection device comprises first and second photodetectors sensitive to two different wavelengths. The two photodetectors are connected to two integration capacitors of two different readout circuits. Two reset circuits are configured so as to initialise the two integration capacitors separately. A first synchronisation circuit is connected to the first readout circuit and to the synchronisation signal and clock signal generators. The first synchronisation circuit is configured in such a way as to
